Property testing in Rust uses proptest to generate random inputs that capture invariants and reproduce bugs across diverse scenarios. It validates discovered bugs by confirming fixes hold under varied conditions, preventing regressions in optimization workflows like hunting and review.

Kani proves bug fixes in Rust code by attempting exhaustive verification of critical execution paths. When feasible, it provides mathematical proofs that confirm the fix holds across all possible inputs, ensuring the regression is fully eliminated.

Yes, you need the Rust toolchain and cargo to run property tests and Kani proofs. The validation workflow requires proptest for property test generation, while Kani is optional and used only when feasible to provide exhaustive verification of critical paths.

The best way to track validated bug fixes is updating assets/db.yaml when validation completes. This records and documents the generated property tests and Kani proofs, enabling team review and maintaining an auditable path from discovery to verified fixes.

Yes, you can use proptest and Kani together for Rust regression testing. Proptest captures invariants and reproduces bugs across random inputs, while Kani attempts exhaustive proofs on critical paths, providing layered verification from probabilistic to mathematical certainty.
